How does beryllium reflect neutrons

WebThe beryllium liner effectively acts as 1) a reflector which directs neutrons back into the plutonium pit; 2) a tamper which initially contains and thereby helps to increase the force … WebOct 31, 2013 · 7. Nuclear reactors are driven away from criticality with the use of control rods which absorb neutrons. In case of overheating and melting of the core, the control rods may not be inserted any more leading to a disaster. A subcritical mass can be made critical by placing neutron reflective material all around it.

WebBeryllium has a large scattering cross section for high-energy neutrons, about 6 barns for energies above approximately 10 keV. Therefore, it works as a neutron reflector and neutron moderator, effectively slowing the neutrons to the thermal energy. WebWhile acting as a neutron shield, the heavy reflector is heated due to the absorption of gamma radiation. The heat in the reflector is removed by water flowing through cooling channels drilled through the reflector to avoid overheating. In fast reactors, moderation of neutrons is undesirable.
